As an exemplary embodiment, the color filter CF may be on the second substrate 112, for example, as in FIG. 3. In another embodiment, the color filter CF may be on the first substrate 111.

The transistor TR is turned on based on a gate signal provided through the gate line GLi. A data voltage received through the data line DLj is provided to the pixel electrode PE of the liquid crystal capacitor Clc through the transistor TR that is turned on. A common voltage is applied to the common electrode CE.

Electric fields are formed between the pixel electrode PE and the common electrode CE based on a difference in voltage level between the data voltage and the common voltage. Liquid crystal molecules in the liquid crystal layer LC are controlled by the electric fields between the pixel electrode PE and the common electrode CE to emit light to form an image.

A storage voltage having a uniform voltage level may be applied to the storage line. In one embodiment, the common voltage may be applied to the storage line. The storage capacitor Cst may supplement a voltage charged in liquid crystal capacitor Clc.

FIGS. 4A and 4B illustrate an embodiment of a connection between the data lines and pixels, for example, corresponding to the display panel of FIG. 1. FIG. 4A illustrates pixels PX on a central portion and a left area LA of the display panel 110. FIG. 4B illustrates pixels PX on a right area RA of the display panel 110.

Referring to FIGS. 4A and 4B, the pixels PX are arranged in a plurality of rows ROW_1 to ROW_m and a plurality of columns COL_1 to COL_n. The rows ROW_1 to ROW_m extend in the first direction DR1. The columns COL_1 to COL_n extend in the second direction DR2. In FIGS. 4A and 4B, the number of rows ROW_1 to ROW_m gradually increases upward. The number of columns COL_1 to COL_n gradually increases in a right direction.

The pixels PX may include a plurality of red pixels to emit red light, a plurality of green pixels to emit green light, and a plurality of blue pixels to emit blue light. In one embodiment, the pixels PX may include a plurality of white pixels, a plurality of yellow pixels, a plurality of cyan pixels, and a plurality of magenta pixels. The pixels PX may be arranged in the order of red, green, and blue pixels in each of the rows ROW_1 to ROW_m, or in a different order in another embodiment.

A number K pixels PX may be in an a-th row of the rows ROW_1 to ROW_m, where a and k are natural numbers. or example, when a is 1, k pixels PX may be in a first row ROW_1 as illustrated in FIGS. 4A and 4B. In another embodiment, the a-th row may be between the first row ROW_1 and an m-th row ROW_m that is the last row. The first row ROW_1 of the rows ROW_1 to ROW_m may be adjacent to the data driver 130. The k pixels PX in the first row ROW_1 may be in a g-th column COL_g to a p-th column COL_p between a first column COL_1 and an n-th column COL_n that is the last column. The values g and p are natural numbers, where g is greater than 1, p is greater than g, and n is greater than p.

Referring to FIGS. 4A and 4B, k pixels PX having the same number as the pixels PX in the first row ROW_1 may be in the m-th row ROW_m. In one embodiment, pixels PX of a number greater than pixels PX in the first row ROW_1 may be in the m-th row ROW_m.

The k pixels PX in the first row ROW_1 may be a reduced or minimum number of pixels in the rows ROW_1 to ROW_m. In FIGS. 4A and 4B, k=9 but k may be a different number in the first row ROW_1 in another embodiment.

The number n pixels PX may be in each of an e-th row ROW_e to an f-th row ROW_f of the rows between the first row ROW_1 and the m-th row ROW_m. In one embodiment, the number n is greater than k, e and f are natural numbers, e is greater than 1, f is equal to or greater than e, and m is greater than f.

The n pixels PX in each of the e-th row ROW_e to the f-th row ROW_f may be a greater or maximum number of pixels PX of the pixels PX in the rows ROW_1 to ROW_m. In FIGS. 4A and 4B, n=27 but may be a different number in each of the e-th row ROW_e to the f-th row ROW_f in another embodiment. In one embodiment, pixels PX of a number greater than k and less than n may be in each of the remaining rows, except for the first row ROW_1, the m-th row ROW_m, and the e-th row ROW_e.

The number of pixels PX in a present row in the rows between the first row ROW_1 and the e-th row ROW_e may be equal to or greater than the number of pixels PX in a former row. In one embodiment, the number of pixels PX in a present row may be the same as the number of pixels PX in the former row.

The number of pixels PX in a present row in rows between the f-th row ROW_f and the m-th row ROW_m may be equal to or less than that of pixels PX in a former row. For example, the number of pixels PX disposed in an f+2-th row may be the same as that of pixels PX in an f+1-th row, and the number of pixels PX in an f+3-th row may be less than that of pixels PX disposed in the f+2-th row.

A number L data lines may be in each of first areas A1, which corresponds to an area between adjacent pixels PX in the first row ROW_1 and an area adjacent to one side of the pixel PX in one column of the first column and the last column of the first row ROW_1, where L is a natural number. For example, an area adjacent to a right side of the pixel PX in the p-th column COL_p, that is the last column of the first row ROW_1, may be or include the first area A1.

The number L may be a value based on dividing the maximum number of pixels PX of the pixels PX in the rows ROW_1 to ROW_m by the minimum number of pixels PX. For example, L may be a value based on dividing n by k. In this case, the number L corresponds to a share of the value obtained by dividing n by k. If a remaining value does not exist when n is divided by k, L data lines may be in each of the first areas A1. However, if a remaining value exists when n is divided by k, other or remaining data lines may be additionally in the first areas A1.

The data lines DL1 to DLn may include a plurality of data line groups DLG which respectively include L data lines. For example, as illustrated in FIGS. 4A and 4B, when n=27 and k=9, L may be determined as 3. Thus, 3 data lines may be in each of the first areas A.

The data lines DL1 to DLn extend in the second direction DR2 in the first areas A1. The data lines DL1 to DLn in the first areas A1 extend to the data driver 130 in the second direction DR2 and are connected to the data driver 130.

The data line groups DLG include a plurality of straight lines SDL and a plurality of bent data lines BDL. The straight lines SDL may be first data lines of the L data lines of each of the data line groups DLG. The bent data lines BDL may be data lines except for the straight lines SDL.

The straight data lines SDL may extend in the second direction DR2 and be connected to the pixels PX in the corresponding column of the g-th column COL_g to the p-th column COL_p. In the first row ROW_1 to the e-th row ROW_e, the bent data lines BDL may be bent twice to extend in the second direction DR2, the first direction DR1, and the second direction DR2. The bent data lines BDL extend from the e-th row ROW_2 in the second direction DR2.

The bent data lines BDL may extend to be bilaterally symmetrical to each other with respect to a predetermined area of a central portion of the display panel 110. The bent data lines BDL may include first to v-th bent data lines BDL1 to BDLv and be connected to the pixels PX that are not connected to the straight data lines SDL.

An area of the display panel 110, which is disposed at a left side with respect to the central portion of the display panel 110 in the first direction DR1, may corresponding to a left area LA of the display panel 110. An area of the display panel 110, which is disposed at a right side with respect to the central portion of the display panel 110 in the direction DR1, may correspond to a right area RA of the display panel 110.

An embodiment of the left area LA of the display panel 110 is in FIG. 4A, and an embodiment of the right area RA of the display panel 110 is in FIG. 4B. The pixels PX in the central portion of the display panel 110 may be arranged in the form of the matrix and may be pixels PX in a g+3-th column to a g+5-th column.

In the first row ROW_1 to the e-th row ROW_e, the number of pixels PX in an h-th row may be different from the number of pixels PX in an h+1-th row, where h is a natural number. In this case, the bent data lines BDL having the same number as a difference between the number of pixels PX in the h-th row and the number of pixels PX in the h+1-th row may extend in the first direction DR1 between the pixels PX in the h-th row and the pixels PX in the h+1-th row.

The bent data lines BDL bent from the second direction DR2 to the first direction DR1 to extend may be bent from the first direction DR1 to the second direction DR2 to extend. Each of the bent data lines BDL extending from the first direction DR1 to the second direction DR2 may be connected to the pixels PX in the corresponding column of the columns COL_1 to COL_n.

The bent data lines BDL in first areas A1 successively extend from the second direction DR2 to the first direction DR1, while increasing in order of the bent data lines BDL from the first bent data line BDL1. Also, the bent data lines BDL in the first areas A1 successively extend from the second direction DR2 to the first direction DR1, while increasing in order of the bent data lines BDL from a v-th bent data line BDLv.

When the number of pixels PX in the h+1-th row is greater, by c, than the number of pixels PX in the h-th row in the left area LA of the display panel 110 and the first row ROW_1 to the e-th row ROW_e, c bent data lines BDL may extend between the pixels PX in the h-th row and the pixels PX in the h+1-th row in the first direction DR1 in the left area LA of the display panel 110 and the first row ROW_1 to the e-th row ROW_e, where c is a natural number.

When the number of pixels PX in the h+1-th row is greater, by d, than the number of pixels PX in the h-th row in the right area RA of the display panel 110 and the first row ROW_1 to the e-th row ROW_e, d bent data lines BDL may extend between the pixels PX in the h-th row and the pixels PX in the h+1-th row in the first direction DR1 in the right area RA of the display panel 110 and the first row ROW_1 to the e-th row ROW_e, where d is a natural number.

For example, the number of pixels PX in the first row RWO_1 may be 9 and the number of pixels PX in the second row may be 15. A difference value between the number of pixels PX in the first row RWO_1 and the number of pixels PX in the second row is 6. Thus, 6 bent data lines BDL may extend in the first direction DR1 between the pixels PX in the first row RWO_1 and the pixels PX in the second row.

Since the pixels are bilaterally symmetrical to each other in FIGS. 4A and 4B, c and d may have the same value, e.g., a value of 3. In one embodiment, when the pixels PX are not bilaterally symmetrical to each other, c and d may have different values.

When c and d have the same value (e.g., 3), three bent data lines BDL may successively be bent to extend from the second direction DR2 to the first direction DR1, while increasing in order of the bent data lines BDL from the first bent data line BDL1. Also, three bent data lines BDL may successively be bent to extend from the second direction DR2 to the first direction DR1, while decreasing in order of the bent data lines BDL from the v-th data line BDLv.

In the left area LA of the display panel 110, a first bent data line BDL1, a second bent data line, and a third bent data line of the bent data lines BDL in the first area A1 to extend in the second direction DR2 are successively bent to extend in the first direction DR1 between the pixels PX in the first row ROW_1 and the pixels PX disposed in the second row.

In the right area RA of the display panel 110, a v-th bent data line BDL1, a v−1-th bent data line, and a v−2-th bent data line of the bent data lines BDL in the first area A1 to extend in the second direction DR2 are successively bent to extend in the first direction DR1 between the pixels PX disposed in the first row ROW_1 and the pixels PX disposed in the second row.

Since the number of pixels PX in the second row is 15 and the number of pixels PX in a third row is 19, a difference value between the number of pixels PX in the second row and the number of pixels PX in the third row is 4. In the left area LA and the right area RA of the display panel 110, fourth and fifth bent data lines and v−3-th and v−4-th bent data lines may successively be bent to extend in the first direction DR1 between the pixels PX in the second row and the pixels PX in the third row.

The bent data lines BDL may be bent to extend from the second direction DR2 to the first direction DR1 in the first row ROW_1 to the e-th row ROW_e through the foregoing manner. The bent data lines BDL extending in the first direction DR1 are successively bent to extend from the first direction DR1 to the second direction DR2 from the first bent data line BDL1 and the v-th bent data line BDLv.

Each of the bent data lines BDL bent to extend from the first direction DR1 to the second direction DR2 is connected to the pixels PX in the corresponding column of a first column COL_1 to a g−1-th column and a p+1-th column to n-th column COL_n. The bent data lines BDL bent to extend from the first direction DR1 to the second direction DR2 are connected by a column unit to the pixels PX successively disposed in an e−1-th column to the first column COL_1 from the first bent data line BDL1 and connected by a column unit to the pixels PX successively disposed in a p+1-th column to n-th column COL_n from the v-th bent data line BDLv.

For example, in the left area LA of the display panel 110, the first, second, and third bent data lines extending in the first direction DR1 between the pixels PX arranged in the first row ROW_1 and the pixels PX in the second row are successively bent to extend from the first direction DR1 to the second direction DR2. In the left area LA and the right area RA of the display panel 110, the first, the second, and the third bent data lines extending from the first direction DR1 to the second direction DR2 are successively connected by a column unit to the pixels PX in an e−1-th to e−3-th columns.

The first bent data line BDL1 extends from the first direction DR1 to the second direction DR2 and is connected to the pixels PX arranged in the corresponding e−1-th column of the first column COL_1 to the e−1-th column. The second bent data line extends from the first direction DR1 to the second direction DR2 and is connected to the pixels PX arranged in the corresponding e−2-th column of the first column COL_1 to the e−1-th column. The third bent data line extends from the first direction DR1 to the second direction DR2 and is connected to the pixels PX arranged in the corresponding e−3-th column of the first column COL_1 to the e−1-th column.

In the right area LA of the display panel 110, the v-th, the v−1-th, and the v−2-th bent data lines BDL may extend in the same manner and are successively connected by the column unit to the pixels PX in a p+1-th, a p+2-th, and a p+3-th columns. Other or remaining ones of the bent data lines BDL may be connected to other or remaining ones of the pixels in the same manner.

For example, the bent data lines BDL may successively extend in the second direction DR2, the first direction DR1, and the second direction DR2 from the first bent data line BDL1 and the v-th bent data line BDLv. In one embodiment, the bent data lines BDL may extend in the second direction DR2, the first direction DR1, and the second direction DR2.

FIG. 5 illustrates an embodiment of L data lines in one first area of FIG. 4A. FIGS. 6 to 8 are views illustrating an example of a distance between pixels in adjacent rows in FIGS. 4A and 4B. Each of FIGS. 6 to 8 illustrates an example of pixels in two rows in the left area LA of the display panel 110 and in the first row ROW_1 to the e-th row ROW_e.

Referring to FIG. 5, L data lines DLj, DLj+1, and DLj+2 in the first area A1 of the first row ROW_1 extend in the second direction DR2 and are at the same distance in the first direction DR1. The data lines adjacent to each other of the data lines DLj, DLj+1, and DLj+2 may be spaced a first distance GP1 from each other in the first direction DR1 in the first area A1.

Each of the data lines DLj, DLj+1, and DLj+2 has a predetermined width WD in the first direction DR1. The distance of sides of the data lines adjacent to each other of the L data lines DLj, DLj+1, and DLj+2 in the first direction corresponds to a pitch PT. The pitch PT may be based on a sum of the first distance GP1 and the width WD.

Referring to FIGS. 6 to 8, the pixels PX have the same size. The pixels PX in an h-th row and the pixels PX in an h+1-th row are arranged in the first direction DR1. The distance between the pixels PX in adjacent rows in the second direction DR2 on the display panel 110 may correspond to a second distance GP2.

The second distance GP2 may be equal to or greater than the product of the pitch PT and the maximum value of a difference value in number of pixels PX in the rows adjacent to each other on the left area LA and in the first row ROW_1 to the e-th row ROW_e or a difference value in number of pixels PX disposed in the rows adjacent to each other on the right area RA and in the first row ROW_1 to the e-th row ROW_e.

As described with reference to FIGS. 4A and 4B, when the pixels PX are bilaterally symmetrical to each other, c and d may have the same value. In the left area LA of the display panel 110 and the first row ROW_1 to the e-th row ROW_e, a difference value in the number of pixels PX in rows adjacent to each other may be 1 to 3. In the right area RA of the display panel 110 and the first row ROW_1 to the e-th row ROW_e, a difference value in the number of pixels PX in rows adjacent to each other may be 1 to 3.

The maximum value of the difference value in number of pixels PX in the rows adjacent to each other on the left area LA of the display panel 110 and in the first row ROW_1 to the e-th row ROW_e and the difference value in number of pixels PX in the rows adjacent to each other on the right area RA of the display panel 110 and in the first row ROW_1 to the e-th row ROW_e is 3. Thus, the second distance GP2 may be equal to or greater than the product of the pitch PT and the value of 3.

When h=1, as illustrated in FIG. 6, the second distance GP2 between the pixels PX in the first row ROW_1 and the pixels PX in the second row ROW_2 may be equal to or greater than the product of the pitch PT and the value of 3, e.g., GP2≥PT×3. When h=2, as illustrated in FIG. 7, the second distance GP2 between the pixels PX in the second row ROW_2 and the pixels PX in the third row ROW_3 may be equal to or greater than the product of the pitch PT and the value 3.

When h is e−1, as illustrated in FIG. 8, the second distance GP2 between the pixels PX in an e−1-th row ROW_e−1 and the pixels PX in an e-th row ROW_e may be equal to or greater than the product of the pitch PT and the value 3. The second distance GP2 between pixels PX in adjacent rows and other or remaining rows may also be equal to or greater than that obtained by multiplying the pitch PT by 3.

The pixels PX may not be disposed bilaterally symmetrical to each other. For example, in the left area LA of the display panel 110 and the first to e-th rows ROW_1 to ROW_e, a difference value in number of pixels PX in adjacent rows may be 1 to 4. In the right area RA of the display panel 110 and the first to e-th rows ROW_1 to ROW_e, a difference value in number of pixels PX in adjacent rows may be 1 to 3. In this case, the second distance GP2 may be equal to or greater than the product of the pitch PT and the value 4.

When an L number of data lines DL1 to DLn are not between the pixels PX of the first row ROW_1, but are disposed one-by-one between the pixels PX of the first row ROW_1, the data lines not between the pixels PX may extend via the non-display area NDA on which the pixels PX are not disposed. Since the space of the non-display area NDA, in which the data lines that are not disposed between the pixels PX that are disposed, is to be secured, the bezel area of the non-display area may increase.

In an embodiment, L number of data lines DL1 to DLn are between the pixels PX of the first row ROW_1. As a result, the bezel area may be reduced. Thus, the display apparatus 100 may realize a narrow bezel.

FIG. 9 illustrates a cross-sectional view of an area B1 of FIG. 4A according to one embodiment. Referring to FIG. 9, one data line extending in the second direction DR2 may cross at least one data line extending in the first direction DR1. The data lines that extend in the first and second directions DR1 and DR2 and cross may be insulated from each other. For example, a j-th data line DLj extending in the second direction DR2 may cross a j+1-th data line DLj+1 extending in the first direction DR1. The j+1-th data line DLj+1 of the j-th data line DLj and the j+1-th data line DLj+1, which cross each other, may include a bridge electrode BE, a first sub line SL1, and a second sub line SL2.

A first insulation layer INS1 is on the first substrate 111, and the j-th and j+1-th data lines DLj and DLj+1 are on the first insulation layer INS1. The first sub line SL1 and the second sub line SL2 of the j+1-th data line DLj+1 are disposed with the j-th data line DLj therebetween. A second insulation layer INS2 is on the first insulation layer INS1 and covers the j-th and j+1-th data lines DLj and DLj+1.

The bridge electrode BE of the j+1-th data line DLj+1 is on the second insulation layer INS2. The bridge electrode BE and the data line DLj may be disposed with the second insulation layer INS2 therebetween. The bridge electrode BE passes through the second insulation layer INS2 and is connected to the first and second sub lines SL1 and SL3 through contact holes CH, which expose predetermined areas of the first and second sub lines SL1 and SL2.

Since the first sub line SL1 and the second sub line SL3 are electrically connected to each other through the bridge electrode BE, the j-th data line DLj extending in the second direction DR2 and the j+1-th data line DLj+1 extending in the first direction DR1 are insulated from each other, even though they cross.

FIGS. 10A and 10B illustrate an embodiment of a connection between data lines and pixels of a display panel. Difference points for the connection between the data lines DL1 to DLn and the pixels PX in FIGS. 4A and 4B and for the connection between data lines DL1 to DLn and pixels PX will be described. For example, FIG. 10A illustrates pixels PX in a central portion and a left area LA of a display panel 110_1. FIG. 10B illustrates pixels PX in a right area RA of the display panel 110_1.

Referring to FIGS. 10A and 10B, the pixels PX are arranged in rows ROW_1 to ROW_m and columns COL_1 to COL_n. Each of the pixels PX in each of the row ROW_1 to ROW_m is connected to a corresponding data line of the data lines DL1 to DLn. The number of pixels PX in each of the first row ROW_1 to an m-th row ROW_m is k. The number of pixels in each of an e-th row ROW_e to an f-th row ROW_f is n. The number of pixels PX in each of other or remaining rows may be less than n and greater than k. In the examples of FIGS. 10A and 10B, k=9 and n=25.

The number of pixels PX in the present row in the rows between the first row ROW_1 and the e-th row ROW_e may be equal to or greater than the number of pixels PX in a former row. The number of pixels PX in the present row in the rows between the f-th row ROW_f and the m-th row ROW_m may be equal to or less than the number of pixels PX in a former row.

A number L data lines corresponding to a value obtained by dividing n by k may be in first areas A1, respectively. A remaining value may be obtained from dividing n by k, e.g., dividing n by k is b, where b data lines may be additionally disposed one-by-one in b first areas A1, where b is a natural number.

A number L+1 data lines may be in each of the b first areas A1 of the first areas A1, and the L data lines may be in each of the other or remaining first areas A1. The number L+1 data lines are successively disposed in w first areas A1 from the most left side of the first areas A1 and successively disposed in b−w first area A1 from the most right side, where w is an integer equal to or greater than 0 and is equal to or less than b.

For example, in the examples of FIGS. 10A and 10B, since n=25 and k=9, a value obtained by n by k is 2 and the remaining value is 7. Thus, L us 2 and b is 7. Also, two data lines are in each of the first areas A1. When w is 4, 4 data lines of 7 data lines are successively disposed, one-by-one, in 4 first areas A1 from the most left side of the first areas A1. Other or the remaining 3 data lines of 7 data lines may be successively disposed, one-by-one, on 3 first areas A1 from the most right side of the first areas A1.

An extending manner of the data lines DL1 to DLn and a distance between the pixels in an h-th row and the pixels in an h+1-th row may be substantially the same as those, for example, described with reference to FIGS. 4A, 4B, and 5 to 8.

For example, as illustrated in FIGS. 4A and 4B, straight data lines SDL in the first areas A1 may extend in the second direction DR2 and be connected to the pixels in a corresponding column of column COL_1 to COL_n. Bent data lines BDL may extend in the second direction DR2, the first direction DR1, and the second direction DR2 and be connected to the pixels in a corresponding column of the column COL_1 to COL_n.

As illustrated in FIGS. 6 to 8, a second distance GP2 between the pixels PX in rows adjacent to each other in the second direction DR2 on the display panel 110_1 may be equal to or greater than that obtained by multiplying the pitch PT by the maximum value of a difference value in number of pixels PX in the rows adjacent to each other on a left area LA of the display panel 110_1 and in the first row ROW_1 to the e-th row ROW_e or a difference value in number of pixels PX in the rows adjacent to each other on a right area RA of the display panel 110_1 and in the first row ROW_1 to the e-th row ROW_e.

In the display apparatus including the display panel 110_1 of FIGS. 10A and 10B, since L or L+1 data lines may be between the pixels PX of the first row ROW_1, a bezel area may be reduced.

FIG. 11 illustrates another embodiment of a display apparatus 200, and FIG. 12 illustrates an embodiment of pixels and data lines in an area A2 of the display panel of FIG. 11. For example, FIG. 12 illustrates pixels PX and data lines, which are in the left area of a display panel 210 in a left side with respect to a central area of the display panel 210. The display panel 210 may have a structure that is bilaterally symmetrical, e.g., pixels PX and data lines in a right area of the display panel 210 may be symmetrical to those in the left area of the display panel 210. Pixels PX in a central area of the display panel 210 may be arranged in the form of a matrix.

Referring to FIGS. 11 and 12, the display apparatus 200 includes the display panel 210, a gate driver 220, a data driver 230, and a flexible circuit board 240. The display panel 210 includes a plurality of pixels PX, a plurality of gate lines GL1 to GLm connected to the pixels PX, and a plurality of data lines DL1 to DLn.

The gate lines GL1 to GLm extend in a first direction DR1 and are connected to the gate driver 220 in an non-display areas NDA at a left side of the display panel 210. The data lines DL1 to DLn are connected to the data driver 230. The data driver 230 is mounted on the flexible circuit board 240 and connected to the non-display area NDA at a lower end of the display panel 210.

The display apparatus 200 may have the same constituent elements as the display apparatus 100 of FIG. 1, except for the shape of the display panel 210 and an arrangement of the pixels PX according to the shape of the display panel 210.

The display panel 210 may have a shape similar to that of a rearview mirror of a vehicle. The display panel 210 includes a first side S1 extending in the first direction DR1, a second side S2 extending in the first direction DR1 facing the first side S1 and having a length less than the first side S1, a third side S3 connecting one side of the first side S1 to one side of the second side S2, and a fourth side S4 connecting the other side of the first side S1 to the other side of the second side S2. Each of a predetermined area of each of both sides of the third side S3 and a predetermined area of each of both sides of the fourth side S4 has a curved shape that protrudes to the outside.

The display panel 210 includes a display area DA and a non-display area NDA surrounding the display area DA. The pixels PX may be arranged in a plurality of rows and plurality of columns in the display area DA. An a-th row may be a first row ROW_1, and k pixels PX may be in the first row ROW_1. A number n pixels PX may be in each of an e-th row ROW_e to an f-th row ROW_f of the rows between the first row ROW_1 and an m-th row ROW_m.

A number r pixels PX number greater than the number k may be in the m-th row ROW_m, where r is a natural number that is greater than k and less than n. The pixel PX having number greater than k and less than n may be in each of rows between the first row ROW_1 and an e-th row ROW_e. A number of pixels PX less than n and greater than r may be in each of rows between an f-th row ROW_f and the m-th row ROW_m.

The number of pixels PX in a present row, in the rows between the first row ROW_1 and the e-th row ROW_e, may be equal to or greater than the number of pixels PX in a former row. The number of pixels PX in a present row, in the rows between the f-th row ROW_f and the m-th row ROW_m, may be equal to or less than the number of pixels PX in a former row.

The arrangement of the data lines DL1 to DLn, the extending manner of the data lines DL1 to DLn, and the distance between the pixels PX in an h-th row and the pixels PX in an h+1-th row may be substantially the same as in FIGS. 4A, 4B, 5 to 8, 10A, and 10B, except for a shape of the display panel 210.

For example, like the arrangement of data lines DL1 to DLn in FIGS. 4A and 4B, L data lines corresponding to a value obtained by dividing n by k may be in each of the first areas A1 of the first row ROW_1. However, when a remaining value obtained by dividing n by k exists, like the arrangement of data lines DL1 to DLn in FIGS. 10A and 10B, b data lines corresponding to the remaining value may be additionally disposed, one-by-one, in each of the first areas A1.

Straight data lines SDL may extend in the second direction DR2 and be connected to pixels PX in a corresponding column of the columns. Bent data lines BDL may extend in the second direction DR2, the first direction DR1, and second direction DR2 and may be connected to pixels in a corresponding column of the columns.

As illustrated in FIGS. 6 to 9, a second distance GP2 between the pixels PX in the rows adjacent to each other in the second direction DR2 on the display panel 210 may be equal to or greater than that obtained by multiplying a pitch PT by the maximum value of a difference value in number of pixels PX in the rows adjacent to each other in a left area LA of the display panel 210 and in the first row ROW_1 to the e-th row ROW_e or a difference value in number of pixels PX disposed in the rows adjacent to each other on a right area RA of the display panel 210 and in the first row ROW_1 to the e-th row ROW_e.

In the display apparatus 200, L data lines are between the pixels PX of the first row ROW_1. As a result, the bezel area may be reduced.

FIG. 13 illustrates another embodiment of a display apparatus 300, and FIG. 14 illustrates an embodiment of pixels and data lines in a display panel of FIG. 13. Referring to FIGS. 13 and 14, the display apparatus 300 includes a display panel 310, a gate driver 320, a data driver 330, and a flexible circuit board 340. The display panel 310 includes a plurality of pixels PX, a plurality of gate lines GL1 to GLm connected to the pixels PX, and a plurality of data lines DL1 to DLn.

The gate lines GL1 to GLm extend in a first direction DR1 and are connected to the gate driver 320 in an non-display areas NDA at a right side of the display panel 310. The data lines DL1 to DLn are connected to the data driver 330. The data driver 330 is mounted on the flexible circuit board 340 and connected to the non-display area NDA at a lower end of the display panel 310.

The display apparatus 300 may have the same constituent elements as the display apparatus 100 of FIG. 1, except for a shape of the display panel 310 and an arrangement of the pixels PX according to the shape of the display panel 310.

The display panel 310 may have a shape similar to that of goggles. For example, the display panel 310 includes a first side S1_1 extending in the second direction DR2, two second sides S1_2 connected to different sides of the first side S1_1 to extend in the first direction DR1, and two curved sides CS1 facing the first side S1_1 and each of which has a curved shape. The curved sides CS1 have sides connected to each other. Each of the curved sides CS1 has one side connected to an end of a corresponding second side S1_2 of the second sides S1_2. Each of the curved sides CS1 has a curved shape that protrudes to the outside of the display panel 310.

The pixels PX may be arranged in a plurality of rows ROW_1 to ROW_m and a plurality of columns COL_1 to COL_n. An a-th row ROW_a may be a row between a first row ROW_1 and an m-th row ROW_m. A number k pixels PX may be in the a-th row ROW_a. A number n pixels PX may be in each of an e-th row ROW_e to an f-th row ROW_f of the rows between the first row ROW_1 and the a-th row ROW_a. A number n pixels PX may be in each of a q-th row ROW_q to an u-th row ROW_u of the rows between the a-th row ROW_a and the m-th row ROW_m. The numbers q an u are natural numbers, u is greater than q, and m is greater than u.

The number of pixels in the first row ROW_1 and the m-th row ROW_m may be r that is greater than k. The pixels PX having number that is greater than k and less than n may be in each of the rows between the a-th row ROW_a and the q-th row ROW_q and the rows between the a-th row ROW_a and the f-th row ROW_f. The pixels PX having number that is greater than r and less than n may be in each of the rows between the first row ROW_1 and the e-th row ROW_e and the rows between the u-th row ROW_u and the m-th row ROW_m. In FIGS. 14, k=7 and n=14.

The number of pixels PX in a present row, in the rows between the first row ROW_1 and the e-th row ROW_e, may be equal to or greater than the number of pixels PX in a former row. The number of pixels PX in a present row, in the rows between the f-th row ROW_f and the a-th row ROW_a, may be equal to or less than the number of pixels PX in a former row.

The number of pixels PX in a present row, in the rows between the a-th row ROW_a and the q-th row ROW_q, may be equal to or greater than the number of pixels PX in a former row. The number of pixels PX in a present row in the rows between the u-th row ROW_u and the m-th row ROW_m may be equal to or less than that of pixels PX in a former row. The pixels PX may be vertically symmetrical to each other in the second direction DR2 with respect to the a-th row ROW_a.

L data lines may be in each of the first areas A1 of the a-th row ROW_. Straight data lines SDL may extend in the second direction DR2 and be connected to the pixels in a corresponding column of the columns COL_1 to COL_n. Bent data lines BDL may be bent at least two times and may extend from the second direction DR2 to the first direction DR1 and from the first direction D1 to the second direction DR2 and be connected to the pixels in a corresponding column of the columns COL_1 to COL_n.

Since k=7 and n=s 14, L is 2. Two data lines may be in each of the first areas A1 of the a-th row ROW_a, and the data lines may extend in the second direction DR2 on the first areas A1.

The pixels PX may not be bilaterally symmetrical to each other. For example, the pixels PX in the row on the right area of the display panel 310 may have the same number, and the pixels in the rows on the left area of the display panel 310 may have numbers different from each other. Thus, the value d provided as an example in FIGS. 4A and 4B may not exist, and only the value c may exist.

In this case, in the first row ROW_1 to the q-th row ROW_q, the data lines having the same number as a difference between the number of pixels PX in the h-th row and the number of pixels PX in the h+1-th row may extend in the first direction DR1 between the pixels PX in the h-th row and the pixels PX in the h+1-th row, where z is a natural number.

The bent data lines BDL in the first areas A1 successively extend from the second direction DR2 to the first direction DR1 from the first bent data line BDL1 of the bent data lines BDL. The bent data lines BDL, bent from the second direction DR2 to the first direction DR1, may be successively bent from the first direction DR1 to the second direction DR2.

For example, in the f-th row ROW_f to the a-th row ROW_a, when a difference value between the number of pixels PX in the h-th row and the number of pixels PX in the h+1-th row is z, z bent data lines BDL may extend in the first direction DR1 between the pixels PX in the h-th row and the pixels PX in the h+1-th row. Each of the z bent data lines BDL extending in the first direction DR1 may extend from the first direction DR1 to the second direction DR2 and be connected to the pixels PX in a corresponding column of the columns COL1 to COLn.

For example, a difference between the number of pixels PX in an a−1-th row and the number of pixels PX in the a-th row ROW_a may be 3. The first to third bent data lines of the bent data lines BDL extending in the second direction DR2 on the first areas A1 may successively extend in the first direction DR1 between the pixels PX in the a−1-th row and the a-th row ROW_a.

The first to third bent data lines extending in the first direction DR1 may successively extend from the first direction DR1 to the second direction DR2. Each of the first to third bent data lines BDL extending from the first direction DR1 to the second direction DR2 may be connected to the pixels PX in the corresponding column.

The number of pixels PX in an a−2-th row and the number of pixels PX in the a−1-th row may be the same. Thus, the bent data line BDL extending in the first direction DR1 between the pixels PX in the a−2-th row and the pixels PX in the a−1-th row do not exist.

In other or remaining rows, except for the a-th to a−2-th rows of the f-th row ROW_f to the a-th row ROW_a, the bent data lines BDL except for the first to third bent data lines may extend from the second direction DR2 to the first direction DR1 in the same manner, and then extend in the second direction DR2. This manner may be substantially the same as the extending manner of the data lines DL1 to DLn described with reference to FIGS. 4A and 4B.

Also, in the e-th row ROW_e to the first row ROW_1, when a difference value between the number of pixels PX in the h-th row and the number of pixels PX in the h+1-th row is z, the bent data lines BDL extend in the first direction DR1 between the pixels PX in the h-th row and the pixels PX in the h+1-th row. For example, since a difference between the number of pixels PX in the e−1-th row and the e-th row ROW_e and the number of pixels PX in the e−2-th row and the e−1-th row is 1, one bent data line BDL extends in the first direction between the pixels PX in the e−1-th row and the pixels PX in the e-th row ROW_e and between the pixels PX in the e−2-th row and the pixels in the e−1-th row. Other bent data lines BDL may be connected in the same manner.

In the e-th row ROW_e to the first row ROW_1, the bent data lines BDL may successively extend from the second direction DR2 to the first direction DR1 from the bent data line BDL at the most left side. For example, the bent data line BDL extending in the second direction DR2 between the pixels PX in the first column COL_1 of the e-th row ROW_e and the pixels PX in the second column may extend in the first direction DR1 between the pixels PX in the e−1-th row and the pixels PX in the e-th row ROW_e.

Next, the bent data lines BDL extending in the second direction DR2 between the pixels PX in the second column of the e-th row ROW_e and the pixels PX in the third column may extend in the first direction DR1 between the pixels PX in the e−2-th row and the pixels PX in the e−1-th row. Other bent data lines BDL may be connected in the same manner.

In the e-th row ROW_e to the first row ROW_1, the bent data lines BDL extending in the first direction DR1 may extend in the second direction DR2 at positions corresponding to positions of the bent data lines BDL in the a-th row ROW_a. For example, a v-th bent data line BDLv is adjacent to a right side of the pixel PX of the n-th column COLn of the a-th row ROW_a.

In the e-th row ROW_e to the first row ROW_1, the v-th bent data line BDLv extending in the first direction DR1 may be adjacent to the right side of the pixels PX in the n-th column COLn of the e−1-th row ROW_e−1 to the first row ROW_1 to extend in the second direction. Other bent data lines BDL may be connected in the same manner. In on embodiment, in the e-th row ROW_e to the first row ROW_1, the bent data lines BDL extending in the first direction DR1 may be in various columns of the e-th row ROW_e to the first row ROW_1 to extend in the second direction DR2.

In the a-th row ROW_a to the q-th row ROW_q, when a difference value between the number of pixels PX in the h-th row and the number of pixels PX in the h+1-th row is z, z bent data lines BDL may extend in the first direction DR1 between the pixels PX in the h-th row and the pixels PX in the h+1-th row. Thereafter, the straight data lines SDL may extend in the second direction DR2 and be connected to the pixels PX in a corresponding row. This manner may be substantially the same as that described with reference to FIGS. 4A and 4B.

The second distance GP2 between the pixels PX in the rows adjacent to each other in the second direction DR2 on the display panel 310 is equal to or greater than that obtained by multiplying a pitch PT by the maximum value of a difference value in number of pixels in the rows adjacent to each other in the first row ROW_1 to the q-th row ROW_q of the display panel 110. For example, in the first row ROW_1 to the q-th row ROW_q, since the maximum value of the difference value in number of pixels PX in the rows adjacent to each other is 3, the second distance GP2 is equal to or greater than that obtained by multiplying the pitch PT by 3.

The data lines DL1 to DLn from the q-th row ROW_q to the m-th row ROW_m extend in the second direction DR2. However, in the e-th row ROW_e to the first row ROW_1, the bent data lines BDL extends from the second direction DR2 to the first direction DR1 and then extends from the second direction DR2 to the first direction DR1. The data lines DL1 to DLn may be connected to the data driver 330 adjacent to the first row ROW_1 via a space between the pixels PX of the first row ROW_1.

The data lines DL1 to DLn having a predetermined number may be between the pixels PX of the first row ROW_1 and connected to the data driver 330 to reduce the bezel area of the display apparatus 300.

FIGS. 15A and 15B illustrate another embodiment of a connection between data lines and pixels of a display panel. FIGS. 16 to 18 illustrate an example of a distance between the pixels in the rows adjacent to each other in the second direction in FIGS. 15A and 15B. For example, FIG. 15A illustrates pixels PX in a central portion and a left area LA of a display panel 410. FIG. 15B illustrates the pixels PX in a right area RA of the display panel 410. Each of FIGS. 16 to 18 illustrates examples of pixels PX in two rows on the left area LA of the display panel 410 and in a first row ROW_1 to an e-th row ROW_e.

Referring to FIGS. 15A and 15B, pixels PX are arranged in a plurality of rows ROW_1 to ROW_m and a plurality of columns COL_1 to COL_n. The arrangement of pixels PX may be substantially the same as the pixels PX in FIGS. 4A and 4 b.

L data lines may be in each of first areas A1 of the first row ROW_1. In FIGS. 15A and 15B, since k=9 and n=28, L may be 3. The data lines DL1 to DLn extend in the second direction DR2 on the first areas A1. An intermediate data line DLc of the data lines DL1 to DLn extends in the second direction DR2. Other or remaining data lines, except for the intermediate data line DLC, may be bent data lines BDL.

In the first row ROW_1 to the e-th row ROW_e, the bent data lines BDL may be bent at least two times and may extend from the second direction DR2 to the first direction DR1, and then from the first direction DR1 to the second direction DR2. The bent data lines BDL extend from the e-th row ROW_2 in the second direction DR2. The bent data lines BDL may have a bent shape that is symmetrical to each other with respect to the intermediate data line DLc.

For example, in the first row ROW_1 to the e-th row ROW_e, the bent data line adjacent to a left side of the intermediate data line DLc may be bent to extend from an upward direction of the second direction DR2 to a left direction of the first direction DR1, and then from the left direction of the first direction DR1 to the upward direction of the second direction DR2. In the first row ROW_1 to the e-th row ROW_e, the bent data line adjacent to a right side of the intermediate data line DLc may be bent to extend from an upward direction of the second direction DR2 to a right direction of the first direction DR1, and then from the right direction of the first direction DR1 to the upward direction of the second direction DR2.

In the first row ROW_1 to the e-th row ROW_e, a first bent data line BDL1 may repeatedly extend in an upward direction of the second direction DR2, the left direction of the first direction DR1, and the upward direction of the second direction DR2. In the first row ROW_1 to the e-th row ROW_e, a v-th bent data line BDLv may repeatedly extend in the upward direction of the second direction DR2, the right direction of the first direction DR1, and the upward direction of the second direction DR2.

Thus, the bent configuration of the bent data line adjacent to the left side of the intermediate data line DLc and the bent data line adjacent to the right side of the intermediate data line may be symmetrical to each other. Also, the bent configuration of the first bent data line BDL1 and the v-th bent data line BDLv may be symmetrical to each other. Also, the bent configuration of other bent data lines BDL may be symmetrical to each other with respect to the intermediate data line DLc.

In the first row ROW_1 to the e-th row ROW_e, the bent data lines BDL having a predetermined number of the bent data lines BDL may extend in the first direction DR1 between the pixels PX in the h-th row and the h+1-th row. In the first row ROW_1 to the e-th row ROW_e, as the number of rows increases, the number of bent data lines BDL extending from the second direction DR2 to the first direction DR1 may increase. For example, although the number of bent data lines extending in the first direction DR1 between the pixels PX in the first row ROW_1 and the pixels PX in the second row is 8, the number of bent data lines BDL extending in the first direction DR1 between the pixels PX in the second row and the pixels PX in the third row increases to 14.

As the number of rows increases, the number of bent data lines BDL extending in the first direction DR1 may increase. The number of bent data lines BDL extending in the first direction between the pixels PX in the e−1-th row and the pixels PX in the e-th row ROW_e may be increased or maximized.

Each of the bent data lines BDL extending in the first direction between the pixels PX in an h-th row and the pixels PX in an h+1-th row may be connected to the pixels PX in a t-th column corresponding to extend in the second direction between the corresponding t-th column and a t+1-th column of columns of the h+1-th row. For example, four bent data lines extending in the first direction between the pixels PX in the first row ROW_1 and the pixels in the second row may be respectively disposed between first and second columns, between second and third columns, between third and fourth columns, and between fourth and fifth columns of the columns of the second row to extent in the second direction DR2.

The bent data lines extending in the second direction DR2 are respectively connected to the pixel PX in the first column, the pixel PX in the second column, the pixel in the third column, and the pixel PX in the fourth column of the columns of the second row. Other bent data lines BDL may also extend in the same manner and be connected to the pixels PX.

Each of the pixels PX in each of the rows in the first row ROW_1 to the e−1-th row may be connected to a corresponding bent data line BDL of the bent data line BDL. The intermediate data line DLc may not be connected to the pixels PX in the first row ROW_1 to the e−1-th row. In the e-th row ROW_e to the m-th row ROW_m, the data lines DL1 to DLn extend in the second direction DR2 and are connected to the pixels in a corresponding column of the columns COL1 to COLn.

Referring to FIGS. 16 to 18, a second distance GP2 between the pixels PX in the rows adjacent to each other in the second direction DR2 on the display panel 410 may be equal to or greater than that obtained by multiplying a pitch PT by a value calculated by adding one to the maximum value of a difference value in number of pixels PX in the rows adjacent to each other on a left area LA of the display panel 410 and in the first row ROW_1 to the e-th row ROW_e or a difference value in number of pixels PX in the rows adjacent to each other on a right area RA of the display panel 410 and in the first row ROW_1 to the e-th row ROW_e.

The maximum value of the difference value in number of pixels PX in the rows adjacent to each other on the left area LA of the display panel 410 and in the first row ROW_1 to the e-th row ROW_e and the difference value in number of pixels PX of the display panel 410 adjacent to each other on the right area RA and in the first row ROW_1 to the e-th row ROW_e is 3. Thus, the second distance GP2 is equal to or greater than that obtained by multiplying the pitch PT by 4.

When h=1, as illustrated in FIG. 16, the second distance GP2 between the pixels PX in the first row ROW_1 and the pixels PX in the second row ROW_2 may be equal to or greater than that obtained by multiplying the pitch PT by 4. When h=2, as illustrated in FIG. 17, the second distance GP2 between the pixels PX in the second row ROW_2 and the pixels PX in the third row ROW_3 may be equal to or greater than that obtained by multiplying the pitch PT by 4.

When h is e−1, as illustrated in FIG. 18, the second distance GP2 between the pixels PX in an e−1-th row ROW_e−1 and the pixels PX in an e-th row ROW_e may be equal to or greater than that obtained by multiplying the pitch PT by 4. The second distance GP2 between the pixels PX in the rows adjacent to each other in other or remaining rows of the display panel 410 may also be equal to or greater than that obtained by multiplying the pitch PT by 4.

As described in FIGS. 4A and 4B, a difference value between the number of pixels PX in the first row ROW_1 to the e-th row ROW_e of the display panel 410 and in the h-th row on the left and right areas LA and RA and the number of pixels PX in the h+1-th row may be c and d. In FIGS. 15A and 15B, since the pixels PX are bilaterally symmetrical to each other, c and d may have the same value.

In this case, line routing parts LRP having the same number as that obtained by adding 1 to one value of c and d may be defined between the pixels PX in the h-th row and the pixels PX in the h+1-th row. The line routing part LRP extends in the first direction DR1. (For convenience of description, the line routing parts LRP are illustrated by dashed dotted lines in FIGS. 16 and 18). Each of the line routing parts LRP may have, for example, the same width as that WD of each of the data lines.

As illustrated in FIG. 16, a difference value between the number of pixels PX in the first row ROW_1 and the number of pixels in the second row ROW_2 on the left area LA of the display panel 410 is 3. hus, fourth line routing parts LRP may be between the pixels PX in the first row ROW_1 and the pixels PX in the second row ROW_2.

As illustrated in FIG. 17, a difference value between the number of pixels PX in the second row ROW_2 and the number of pixels in the third row ROW_3 on the left area LA of the display panel 410 is 2. Thus, three line routing parts LRP may be between the pixels PX in the second row ROW_2 and the pixels PX in the third row ROW_3.

As illustrated in FIG. 18, a difference value between the number of pixels PX in the e−1-th row ROW_e−1 and the number of pixels in the e-th row ROW_e on the left area LA of the display panel 410 is 1. Thus, two line routing parts LRP may be between the pixels PX in the e−1-th row ROW_e−1 and the pixels PX in the e-th row ROW_e.

When the pixels PX are not bilaterally symmetrical to each other, c and d may have values different from each other. In this case, the line routing parts LRP having the same number as that obtained by adding 1 to a relatively large value of c and d may be between the pixels PX in the h-th row and the pixels PX in the h+1-th row.

The bent data lines BDL extending in the first direction DR1 extend via the line routing parts LRP. For example, as illustrated in FIG. 16, the bent data lines BDL extending in the first direction DR1 between the pixels PX in the first row ROW_1 and the pixels in the second row ROW_2 may extend via four line routing parts LRP.

As illustrated in FIG. 17, the bent data lines BDL extending in the first direction DR1 between the pixels PX in the second row ROW_2 and the pixels in the third row ROW_3 may extend via three line routing parts LRP. As illustrated in FIG. 18, the bent data lines BDL extending in the first direction DR1 between the pixels PX in the e−1-th row ROW_e−1 and the pixels in the e-th row ROW_e may extend via two line routing parts LRP.

In the display panel 410 of FIGS. 15A and 15B, since L data lines DL1 to DLn are between the pixels PX of the first row ROW_1, the bezel area may be reduced.
